Standing in front of a filing cabinet, Zhou Taifu looked strange, with Yu Wen beside him.

It was very dark here, the only light source coming from the phone in Yu Wen's hand.

Their faces were hidden in the darkness.

"How could this be?" Yu Wen looked at the scene before her, her eyebrows furrowing slightly, the composure in her expression gone.

The filing cabinet was divided into 4 layers, from top to bottom.

Except for the first layer, which showed no signs of having been touched, the other three layers had been rummaged through, with many kraft paper bags scattered on the ground.

Zhou Taifu crouched down and touched them.

There was no dust on the paper bags, so this must have happened recently.

In other words, Luo Yi did it.

It seemed he had taken the clues about the female ghost from here.

But...they had searched again just now and found nothing.

Zhou Taifu slowly stood up, his voice chilling, "It seems the ghost took the clues."

This was the situation he least wanted to see.

Midnight tomorrow was the final deadline.

They didn't have much time left.

"Let's go," Yu Wen said without hesitation, turning and walking out.

Zhou Taifu followed behind her, hesitating, "Where to? The equipment center?"

"Building C, the music classroom."

After closing the door, the two quickly disappeared at the end of the corridor...

Silence returned here.

A few minutes passed.

A very slight rubbing sound rang out, and a closed door was pushed open a crack.

This door was located opposite the file room.

Looking inconspicuous.

After a while, a bloodshot eye slowly appeared in the crack of the door.

The eye looked left and right, turned its head, and whispered, "Doctor, they're gone."

Jiang Cheng sat up from a dusty wicker chair, first patting the dust off his butt after getting up, with a kraft paper bag tucked under his arm.

Looking closely, one could still see traces of blood on the corner of the paper bag.

"Doctor," Fatty swallowed and looked at Jiang Cheng, his expression fawning and admiring, and said, "You're really amazing. How did you know they would come to the file room to look for clues?"

"Luo Yi was replaced by a ghost, so they would naturally think he died in the file room, and then think that he might have found some important clues and was silenced by the ghost," Jiang Cheng replied simply.

"But..." Fatty was puzzled for a while, then looked up and asked, "They don't have a camera, how did they confirm that Luo Yi was disguised by a ghost?"

Jiang Cheng took the kraft paper bag in his hand, the seal had been torn open, obviously Luo Yi had already seen the contents.

"It's a mirror," Jiang Cheng said, turning the kraft paper bag over, a small booklet slid out, Jiang Cheng opened it while casually replying, "I saw Zhang Yinyin use it, you can also verify ghosts through mirror reflections."

Hearing Jiang Cheng mention Zhang Yinyin, Fatty suddenly realized that he hadn't seen this woman just now.

"Doctor," Fatty looked at the door, his tone strange, and said, "That Zhang Yinyin is separated from them."

"Yes." Jiang Cheng nodded, he looked at the position of the door, his sight seemed to be able to penetrate the door and see the scene outside, after a moment, he said, "The time is almost up."

Although he didn't understand Jiang Cheng's words, Fatty instinctively felt that there were some profound and complex issues mixed in.

And he understood that even if he asked, Jiang Cheng would not explain it to him.

This was a strange and extremely self-centered man.

The code of conduct that drove him was not something he could understand.

Just on the way here, the moment Jiang Cheng grabbed his collar, looked down, and stared at him, he even felt that the former would kill him.

"Doctor," he carefully changed the subject, craned his neck, looked at the booklet in Jiang Cheng's hand and asked, "What's written in here?"

Jiang Cheng handed the booklet over casually.

The booklet was not big, and not thick even with the cover, with the words "Student Files of the 09th Dance Department" written on it in gold letters.

Just as Yu Wen had guessed, after the ghost killed Luo Yi, it took the file from his hand and put it back in place.

It was just a pity that finding the way and getting rid of Zhang Yinyin wasted too much of their time.

Resulting in Jiang Cheng getting there first and taking the file one step ahead.

And when he heard someone coming upstairs, he hid in the small room opposite the file room.

This should have been an office, not large in scale, but well-equipped.

Jiang Cheng's eyes scanned around.

The only window in the room was covered by dark curtains, and only a little light could penetrate through the gap in the middle.

A dark brown bookcase stood against the wall, next to a white water dispenser.

At the moment, the water in the water dispenser had long since dried up.

4 or 5 empty buckets that had been replaced were placed on the ground.

The empty buckets were overturned to one side, so dirty that one could not see their original color.

Several red clay pots used to grow flowers were neatly arranged in a row under the window.

The plants inside had long since withered beyond recognition.

Behind Fatty, there was also a wooden coat rack with a few clothes hanging on it.

There was a desk calendar on the old desk. Jiang Cheng hadn't seen such a thing in a long time. He picked up the calendar and found that the last time recorded on it was December of 09.

"Doctor," Fatty also noticed the calendar on the desk, frowning deeply, "The person in this office seems to have left in a hurry, none of the things inside were taken away."

December 09...

Jiang Cheng seemed to be thinking.

Fatty held the file in his hand, wondering, "Why, does this college even have a dance department?"

Fatty remembered that this was a specialized music college, and the teacher who brought them in had introduced it that way.

"Yuying Music College naturally doesn't have a dance department, but Yuying Art College does," Jiang Cheng replied, "That's the predecessor of this college."

Fatty was stunned when he heard this.

"It's in the file," Jiang Cheng replied casually.

Reopening the file, Fatty found the name of Yuying Art College inside.

"When did it change its name?"

"Ten years ago, I found the files from 10 years ago in the place where the files were stored, and the name had already been changed to Yuying Music College at that time," he paused, looked at Fatty, and said meaningfully, "The dance department was also cancelled."

Fatty seemed to smell something imperceptibly.

The school suddenly changed its name, the dance department that was cut, the obscure files... all of this seemed to indicate that there was some unknown secret hidden here.

Especially... when thinking of the female ghost who was dancing ballet.

"It was the death of that girl that triggered this series of changes!" Fatty clenched the file and said with certainty.
